Lithofacies of the Devonian Marcellus Shale In the Eastern Appalachian Basin, U.S.A.

Journal of Sedimentary Research, 2015
The Marcellus Shale is an important hydrocarbon source rock and an unconventional reservoir whose origin has engendered much recent debate among geologists. Our analysis of the formation in West Virginia and adjacent States aims to identify and describe the several lithofacies in the eastern Appalachian basin and to interpret their depositional setting.

Quantitative calculated shale gas contents with different lithofacies: A case study of Fuling gas shale, Sichuan Basin, China

Journal of Natural Gas Science and Engineering, 2020
Abstract To accurately evaluate pore structure and gas content characteristics of shale reservoir, a series of tests, including XRD, TOC, porosity, FE-SEM, N2 and CO2 adsorption, and high-pressure methane sorption, were conducted on the Wufeng-Longmaxi shale in the Fuling area.

Lithofacies and Depositional Environments of Monterey Shale, California: ABSTRACT

AAPG Bulletin, 1981
The Miocene Monterey Formation records the deep basinal phase of a major late Tertiary cycle of basin formation and filling associated with wrench fault tectonism. Over much of coastal California, Neogene facies show a progression from Oligocene nonmarine and neritic rocks to Miocene basinal shales and siliceous rocks and then to upper Miocene to ...

Shale Gas Lithofacies Classification and Gas Content Prediction Using Artificial Neural Network

Proceedings, 2016
Here, we show the contribution of the artificial intelligence such as neural network to predict the lithofacies in the lower Barnett shale gas reservoir. The Multilayer Perceptron (MLP) neural network with Hidden Weight Optimization Algorithm is used.

Quantitative Lithofacies and Biofacies Study of Florena Shale (Permian) of Kansas

AAPG Bulletin, 1955
The purpose of this study is to test the practicality and scientific potential of an analytical technique designed to produce quantitative data on biofacies and lithofacies changes. The unit selected for analysis is the Florena shale member of the Beattie limestone (Wolfcampian), a fossiliferous unit traceable across Kansas from Nebraska to Oklahoma ...

On the Zechstein Copper Shale lithofacies and palaeoenvironments in SW Poland

Geological Society, London, Special Publications, 1986
Summary Microfacies and geochemical studies on the Copper Shale in the Sudetic Foreland of SW Poland show the strong influence of palaeorelief on the distribution of lithofacies. Spatial variability in microlithofacies and lithofacies indicate sedimentation in the following palaeoenvironments: (1) offshore—deep shelf, characterized by the ...

Marcellus Shale Lithofacies Prediction by Multiclass Neural Network Classification in the Appalachian Basin

Mathematical Geosciences, 2012
Marcellus Shale is a rapidly emerging shale-gas play in the Appalachian basin. An important component for successful shale-gas reservoir characterization is to determine lithofacies that are amenable to hydraulic fracture stimulation and contain significant organic-matter and gas concentration.

A Close Relationship between Lithofacies, Mineralogy and Pore Characteristics, Horn-River Shale, Canada

78th EAGE Conference and Exhibition 2016, 2016
Summary We performed sedimentologic, petrographical and petrophysical analyses of cores from Horn river shale, Canada. According to the analysis results, formations with higher contents of quartz and subordinating LM-1 and HM facies shows larger pores and higher porosity, and the reverse is true.
